Highly stretchable, hair-compatible multichannel neural interface with time-stable hydrogel for high-fidelity long-term EEG sensing.

A reusable research interface maintained EEG contact through hair during repeated laboratory recordings and online BCI tasks. Home use, clinical monitoring and comfort still require broader testing.

Modalities

EEG, Brain-computer interface, Wearable sensing

Clinical focus

Hair-compatible electrodes, Longitudinal EEG, Reusable neural interfaces

Population

Participants completing longitudinal motor-imagery recordings and repeated online brain-computer-interface experiments

Sample

Human participant denominator and demographic details were not provided in the checked abstract

Intervention / method

A kirigami-patterned elastomeric mesh, deformable liquid-metal interconnects and detachable hydrogel conical electrodes were evaluated for mechanical adaptability, contact stability, longitudinal motor-imagery EEG and repeated online BCI use

Comparator

The abstract describes mechanical and longitudinal performance but does not expose a conventional wet-electrode or commercial-cap comparison

Clinician summary

The MindStretcH prototype preserved electrical performance under deformation and produced consistent task-related activity across longitudinal motor-imagery recordings and repeated online BCI experiments, without measurable recording-quality deterioration in the reported tests.

How to interpret the findings

The abstract omits participant number, demographics, recording duration, quantitative signal metrics, comfort results and direct comparison with standard systems. Laboratory consistency does not establish long-term clinical reliability, home usability, manufacturing reproducibility or regulatory status.

Equipment and disclosures

MindStretcH is the source-named research prototype integrating a kirigami elastomer mesh, eutectic gallium-indium interconnects and detachable hydrogel conical electrodes. It is not presented here as a commercial or cleared medical device.

Competing-interest details were not available in the checked abstract. Crossref lists multiple public, academic and philanthropic awards, including NSF, NIH, UT Austin and Alzheimer's Association support.
